Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 2 to 3, the utility model discloses an automatic riveting device in mould, including riveting mould placed in the middle and a plurality of feeders that provide the riveting subassembly respectively around riveting mould setting (be used for providing the first feeder 21 of riveting 11 and be used for providing by the second feeder 22 of riveting 12), riveting mould includes lower mould 3 and last mould 4, the pay-off face of feeder is located between lower mould 3 and last mould 4, lower mould 3 has a rotary disk 31 through the pin joint of vertical rotary rod 311, rotary rod 311 is driven by the power device 32 of steerable corner, it is equipped with can drive the descending clamp plate 41 of rotary disk 31 to go up mould 4, the last axle equipartition of rotary disk 31 has the same blank riveting cutting die 312 (here is two) with feeder quantity, blank riveting cutting die 312 has blank function and riveting function. The riveting die is in fact a continuous die with stations arranged on a circumference. The specific working principle is as follows: the rotating disc 31 stays at the initial position first, so that one blanking riveting cutter die 312 is positioned below the material belt of the riveted object 11 sent by the first feeder 21, and the other blanking riveting cutter die 312 is positioned below the material belt of the riveted object 12 sent by the second feeder 22; then, the blanking riveting cutting die 312 below the material belt of the riveting object 11 is closed for the first time, so that the material belt of the riveting object 11 is cut off from the material belt and directly falls on the blanking riveting cutting die 312; then the power device 32 drives the rotating disc 31 to rotate 180 degrees so as to change the positions of the two blanking riveting cutting dies 312, the cut-off riveting objects 11 reach the lower part of the material belt of the riveting objects 12, and the rivets are also sent to the riveting dies at the moment, and the riveting of the two dies is finished while the dies are closed. Therefore, the riveting of the previous product and the cutting of the riveting object 11 of the next product are finished by one-time die assembly, the process is continuous, the manufacturing is rapid, and the positioning is convenient. Therefore, the rotary disc riveting device rivets through the rotary disc with the material cutting riveting cutting die, improves riveting efficiency, facilitates riveting positioning and improves riveting precision.

As shown in fig. 2 and 3, the feeding machine includes a first feeding machine 21 and a second feeding machine 22, the first feeding machine 21 and the second feeding machine 22 are arranged in parallel, and two blanking riveting dies 312 arranged at 180 ° are provided on the rotating disc 31. Generally, at least two parts are riveted, so that at least two feeders are used for completing the riveting operation. However, if there are more complex parts of a particular configuration, it is contemplated that more feeders and stations may be used to accomplish this.

As shown in fig. 2, the lower mold 3 is provided with a floating movable striking rod 33, and the upper side of the movable striking rod 33 abuts against the lower surface of the rotating disk 31. The movable striking rod 33 is used as an auxiliary for stripping, and when the mold is opened, the movable striking rod 33 can provide a force on the periphery of the rotating disk 31 to jack the rotating disk 31.

As shown in fig. 2, the top of the movable striking rod 33 is horizontally pivoted with a roller 331 contacting with the rotating disc 31. When the mold is opened, the rotating disc 31 rotates around the vertical axis, and the movable striking rod 33 will move relatively, and the roller 331 can make the two generate smaller rolling friction force, so that the mechanism can run more smoothly.

As shown in fig. 2, the lower mold 3 is provided with a lower positioning post 34 for guiding the position of the rotary platen 31 and the tape at the time of mold clamping, and the upper mold 4 is provided with an upper positioning post 42 for guiding the position of the rotary platen 31. The upper and

lower retention posts

42, 34 allow the tape to be in the proper relative position to the rotary disc 31 to ensure that the product is cut and riveted in place.

As shown in fig. 2 and 3, the edge of the rotating disc 31 is provided with a sensing block (not labeled), one side of the riveting die is provided with a sensor 5 for detecting the position of the sensing block, and the sensor 5 is used for controlling the rotation angle of the power device 32. The normal work of this device relies on the rotation precision of rotary disk 31, and it can be more accurate to make thick location to come to respond through inductor 5, like this reuse spacing post 42 and lower spacing post 34 location just can crashproof mould.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
